How much does a crypto offramp API cost? fees, integration pricing, and build vs. buy
Last updated: April 14, 2026
The cost of adding crypto-to-fiat conversion to your app depends on whether you build it yourself or integrate an offramp API. Building in-house means licenses, banking partnerships, compliance infrastructure, and engineering time measured in years. An API integration means per-transaction fees and a go-live timeline measured in days.
This guide breaks down the real costs of both paths, compares pricing across the four most evaluated offramp API providers in 2026, and gives you a framework for calculating total cost of ownership. If you are new to offramp infrastructure, start with our guide on what a crypto offramp SDK is and how it works.
The global crypto off-ramp market reached $16.2 billion in 2024 and is projected to hit $48.2 billion by 2033 at 14.8% CAGR (Dataintelo, 2025). With over 560 million crypto holders worldwide, the cost of your offramp infrastructure directly affects unit economics at scale.
Offramp API fee comparison: April 2026
Per-transaction fees are the primary cost for any team using an offramp API. The spread across providers is significant, ranging from 0.49% to 4.5%.
| Provider | Base transaction fee | Partner markup | Setup fee | Payout speed |
|---|---|---|---|---|
| Spritz SDK | 0.5% to 1.5% | Optional; partners set their own fee | $0 | Same-day to next-business-day |
| Transak | ~1% base | Available | Not publicly listed | Minutes (instant offramp) |
| MoonPay | Up to 4.5% | Available | Not publicly listed | 3 to 4 business days (bank) |
| Ramp Network | 0.49% to 2.9% | Available | Not publicly listed | 2 to 5 minutes (instant) to 2 business days |
Source: public documentation and pricing pages as of April 2026. Actual rates may vary based on volume, region, and payment method.
At $1 million in monthly offramp volume, the fee difference between providers is substantial. A team paying 0.5% (Spritz low end) spends $5,000 per month in transaction fees. A team paying 4.5% (MoonPay upper bound) spends $45,000. That $40,000 monthly difference compounds to $480,000 annually, enough to fund an entire engineering team.
What drives offramp API pricing
Transaction fees are not the only cost. Four factors determine what you actually pay.
Per-transaction fees
Every offramp provider charges a percentage of the conversion amount. This is the most visible cost and the one that scales directly with volume. Spritz SDK charges 0.5% to 1.5%, with the exact rate depending on the payment method and transaction type. Transak charges approximately 1% as a baseline. Ramp Network ranges from 0.49% to 2.9% depending on region and method. MoonPay charges up to 4.5%.
The variance matters more as volume grows. At low volume (under $100K monthly), the difference between 0.5% and 2.9% is a few hundred dollars. At $5 million monthly, it is the difference between $25,000 and $145,000 in monthly fees.
Partner markup and revenue
Most offramp APIs let partners add their own fee on top of the base transaction rate. This is how apps monetize offramp transactions. If the base fee is 1% and you add a 0.5% markup, your users pay 1.5% total and you keep the 0.5%.
Spritz SDK provides full transparency on this: partners set their own markup, receive monthly payouts, and get complete transaction reporting. The markup model means offramp is not just a cost center; it can be a revenue line for your app.
Setup and integration costs
Some providers charge a one-time setup or integration fee. Spritz SDK charges no setup fee. Other providers do not publicly list their setup fees, which typically means the cost is negotiated based on the scope of integration.
The more meaningful integration cost is engineering time. Widget-based integrations (Transak, MoonPay, Ramp) can go live in a few days with minimal engineering effort. A headless SDK integration like Spritz gives you full UX control but requires more front-end development. Spritz partners typically go live in about 10 days including sandbox testing and compliance review.
Ongoing operational costs
After launch, the provider handles compliance, customer support, and transaction monitoring. These are costs you would otherwise bear in-house. Spritz SDK includes managed services covering KYC/AML, dispute handling, chargeback management, and end-user customer support through what it calls Lightning Managed Services. This means no additional vendor contracts for compliance or support infrastructure.
Build vs. buy: the real cost comparison
The alternative to an offramp API is building your own crypto-to-fiat infrastructure. Here is what that actually involves.
Building in-house
Money transmission licenses alone require state-by-state applications in the US. As of 2026, there are 49 state-level MTL jurisdictions, each with its own application process, bonding requirements, and renewal timelines. Add banking partnerships, KYC/AML vendor contracts, compliance staff, and ongoing regulatory maintenance, and you are looking at 12+ months and $500K+ before you process a single transaction.
That $500K+ figure breaks down roughly as follows.
| Cost category | Estimated range | Timeline |
|---|---|---|
| Money transmission licensing (US) | $100K to $250K+ | 6 to 18 months per state |
| Banking partnership setup | $50K to $100K | 3 to 6 months |
| KYC/AML vendor integration | $30K to $75K | 1 to 3 months |
| Compliance staff (annual) | $150K to $300K | Ongoing |
| Engineering build (core infrastructure) | $200K to $500K | 6 to 12 months |
| Ongoing maintenance and audits | $100K to $200K/year | Ongoing |
These are conservative estimates based on publicly reported costs from companies that have built in-house crypto payment infrastructure. The total first-year cost for a US-focused build easily exceeds $500K, and ongoing costs run $250K to $500K annually before you factor in engineering maintenance.
Using an offramp API
With an API integration, the provider absorbs all licensing, compliance, banking, and support costs. Your costs are the per-transaction fee plus your engineering time to integrate.
| Cost category | Estimated range | Timeline |
|---|---|---|
| Per-transaction fees | 0.5% to 4.5% of volume | Ongoing |
| Setup / integration fee | $0 to $25K | One-time |
| Engineering integration time | 1 to 3 weeks | One-time |
| Ongoing maintenance | Minimal (provider handles updates) | Ongoing |
For a team processing $1 million monthly at 1% fees, the annual cost is approximately $120,000 in transaction fees. Compare that to $500K+ in year one for building in-house, plus $250K+ in annual ongoing costs. The API path breaks even in the first month.
Break-even analysis
The math shifts at very high volume. If you process $50 million monthly, even a 0.5% transaction fee costs $250,000 per month ($3 million annually). At that scale, the in-house build starts to make financial sense, assuming you have the 12 to 18 months and the team to execute it.
For most teams processing under $10 million monthly, the API integration is more cost-effective by a wide margin. fomo.family, a copy-trading app, evaluated multiple providers and went live with Spritz SDK in two weeks, processing over $2 million in withdrawals with 4,000+ users in its first two weeks live. Building that infrastructure in-house would have taken months and delayed their entire product launch.
Hidden costs most teams miss
Beyond the headline fee percentages, several costs catch teams by surprise.
Token swap costs
If your offramp provider only supports a limited set of tokens, users holding other assets need to swap before they can cash out. Each swap incurs gas fees and potential slippage. On Ethereum mainnet, a single swap can cost $5 to $50+ in gas depending on network congestion.
Spritz SDK sidesteps this problem with 50,000+ tokens supported through permissionless DEX routing. Users offramp directly from whatever they hold without an intermediate swap step. For a detailed comparison of token coverage across providers, see our offramp API comparison.
Slow payouts and support overhead
MoonPay's bank transfer payouts take 3 to 4 business days. Every day a user waits for their money is a day they might open a support ticket. Support costs scale with payout delays. Same-day or next-business-day settlement (Spritz, Ramp instant) reduces this overhead significantly.
Widget UX friction
Widget-based integrations redirect users to a third-party checkout flow. This introduces friction that reduces conversion rates. Teams that need a seamless, branded experience end up rebuilding around the widget or switching to a headless integration. That rework has real cost in engineering hours and delayed launches.
Compliance scope changes
Regulatory requirements change. If your provider does not handle compliance end-to-end, you absorb the cost of staying current. Spritz SDK manages all compliance updates, licensing renewals, and regulatory changes as part of the base integration. Partners never need to hire a compliance officer or engage outside counsel for offramp-related regulatory work.
Total cost of ownership framework
Use this framework to compare providers on a like-for-like basis. Most teams only look at the transaction fee percentage, which is one of five cost dimensions.
| Cost dimension | What to calculate | Where to find data |
|---|---|---|
| Transaction fees | Monthly volume x fee percentage | Provider pricing page or sales quote |
| Partner revenue offset | Monthly volume x your markup percentage | Your pricing model |
| Integration engineering | Hours x loaded engineering cost | Your team's estimate |
| Ongoing support and maintenance | Support tickets x cost per ticket, plus engineering hours for provider updates | Your support and engineering data |
| Hidden costs (swaps, delays, rework) | Gas fees for pre-swaps + support cost from slow payouts + UX rework hours | Estimated from token coverage, payout speed, and integration model |
The net cost is: transaction fees minus partner revenue, plus integration cost, plus ongoing costs, plus hidden costs. Teams that only compare transaction fee percentages miss the full picture.
Choosing a pricing model that fits your app
The right offramp API depends on your volume, user base, and product roadmap.
For apps processing under $1 million monthly with price-sensitive users, the lowest base fee wins. Spritz (0.5% to 1.5%) and Ramp (0.49% to 2.9%) are the most competitive options. MoonPay's up to 4.5% fee will reduce conversion rates for cost-conscious users.
For apps that want to monetize offramp transactions, the partner markup model matters more than the base fee. A provider charging 1% base with a flexible markup option can generate more net revenue than a provider charging 0.5% with no markup control. Spritz SDK gives partners full control over their markup with transparent reporting and monthly payouts.
For apps with roadmaps that include bill pay, card issuance, or real-world spending, choosing a provider that bundles these features avoids the cost of integrating multiple vendors. Spritz SDK includes bill pay (credit cards, mortgages, student loans, utilities) and virtual card issuance in the same integration. Every other major provider requires separate vendor contracts for those capabilities.

Frequently asked questions
How much does it cost to integrate a crypto offramp API?
Per-transaction fees range from 0.49% to 4.5% depending on the provider. Spritz SDK charges 0.5% to 1.5% with optional partner markup. Setup fees range from $0 to $25K depending on the provider. Engineering integration typically takes 1 to 3 weeks. The total first-year cost for an API integration is a fraction of the $500K+ required to build in-house.
What are Spritz SDK fees for offramp transactions?
Spritz SDK charges 0.5% to 1.5% per offramp transaction, with the exact rate depending on payment method and transaction type. There is no setup fee. Partners can set their own markup on top of the base fee and receive monthly payouts with full transaction reporting.
Is it cheaper to build an offramp in-house or use an API?
For most teams, an API is significantly cheaper. Building in-house costs $500K+ in year one (licensing, banking partnerships, compliance, engineering) plus $250K+ annually in ongoing costs. An API integration costs engineering time upfront (1 to 3 weeks) plus per-transaction fees (0.5% to 4.5% of volume). The in-house build only becomes cost-competitive at very high volume, typically above $50 million monthly.
Which offramp API has the lowest fees?
As of April 2026, Ramp Network offers the lowest base rate starting at 0.49%, followed by Spritz SDK at 0.5% to 1.5%. Transak charges approximately 1%, and MoonPay charges up to 4.5%. The base fee is only one cost factor; token coverage, payout speed, and integration model also affect total cost of ownership.
Can I make money from offramp transactions in my app?
Yes. Most offramp API providers let partners add their own transaction markup on top of the base fee. Spritz SDK gives partners full control over their markup, with transparent reporting and monthly payouts. The markup model turns offramp from a pure cost into a revenue line.
How long does it take to go live with a crypto offramp API?
Spritz SDK partners typically go live in about 10 days, including sandbox testing, KYB review, and compliance setup. Widget-based providers (Transak, MoonPay, Ramp) can be faster for initial setup (days to a week) since widgets require less front-end development. Headless SDK integrations like Spritz take slightly longer but give full UX control.
